I seem to remember that Riley's had their factory South of the railway line just West of Dulwich Hospital. Makers of horse-riding helmets, motor-cycle helmets (old-style), and industrial protection helmts. Those were the days of leather and cork. This thread reminds me of the difficulties of claiming compensation from the War Damage Commission. Inadequate compensation and material shortages meant that damaged houses next to bomb-sites were "repaired" in a very ad hoc fashion and then the repairs were skillfully hidden. Probably in the hope that proper repairs could be done later in better times. In the old days when East Dulwich had proper estate agents such as White Dent they had this local knowledge of which properties were affected in this way. I suspect that now this local knowledge is lost house surveys may well not discover this damage.
